NOZZLE FOR MILK-CAN CLEANERS.

Application filed August 28, 1924.

To all whom it may concern:

Be it known that I, DEDRIOK A. liLlAAIQUM, a citizen of the UnitedStates, residing at l /linncapolis, in the county of Hennepin and Stateof lslinnesota, have invented certain new and useful Improvements in aNozzle for Millr-Can Cleaners; and I do hereby declare the following tobe'a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to a nozzle, and while the nozzle may be used invarious places, it is particularly designed for use with a machine forcleaning and sterilizing milk cans. These cans are inverted in abasin-like member above which the nozzle is disposed and hot water isforced through the nozzle against the inside of the can. It is desirablethat all parts of the interior of the can be engaged by the sterilizingfluid. It is well known that the ordinary milk can has a convergingportion adjacent the neck thereof and it is desirable that some waterfrom the nozzle be directed downwardly against this converging portion.

It is an object of: this invention therefore to provide a nozzle throughwhich hot water 39 may be forced and which will spray said wateroutwardly in substantially radial directions, some of the jets beingdirected downwardly.

It is a further object of the invention to provide a nozzle having abody portion adapted to be attached to the water supply means andcomprising a check valve, said nozzle having a cylindrical spray head,at its upper end having a semi-spherical top in which a multiplicity ofholes are formed.

It is also an object of the invention to provide a simple and efficientstructure for holding said spray head in place and to provide anefiicient arrangement of the holes therein.

These and other objects and advantages of the invention will be fullyset forth in the following description made in connection with theaccompanying drawings in which like reference characters refer to thesame parts throughout the different views, and in which,

Fig. 1 is a vertical central section through the nozzle;

lie;

shown 5 is a central vertical section of the head, 4t and 5 being shownin ng to the drawings, a nozzle is comprising a body portion 6 ofconpassage and close the same.

The body portion (3 is exteriorly threadedadjacent its upper end and hasa downwardly beveled upper surface. A spray head 9 is provided ofcylindrical form having a semispherical top portion. The said spray headhas an outwardly and downwardly flaring flange 10 at its lower edgeadapted to contact with the beveled top surface of body member 6. Asshown in Fig. 5, spray head 9 is formed of thin sheet materialpreferably brass. A

collar 11 having an inturned flange at its upper end is screwed onto thebody 6 and said flange pressed. the

flange 10 of the spray head tightly downon the beveled top surface ofmember (5. The collar 11 is shown as having its exterior surface knurledso that it can be conveniently gripped and turned. The spray head 9 isprovided with a plurality of rows of circumferentially spaced holes 12extending therethrough.

These holes in the upper port-ion of the head extend substantiallyradially of this semispherical portion but the lower row of holes whichis disposed below the center of the semi-spherical portion are directedoutwardly and downward- 1y, as shown in Fig. 5.

The holes 12 are equally spaced along the periphery of the spray head 9or along a great circle of said periphery. This results in the holesbeing arranged in rows along great circles passing through the topcentral portion of the spray head and also results in the holes beingcloser together circumferentially in the various horizontal rows.

In the operation of the nozzle in the milk can cleaning machine, thesame is connected to a pumping means. hen the hot water is forced upwardthrough the body 6, ball 8 is lifted from its seat and the hot waterforced and sprayed out through the holes 1.2. The projected jets, asstated, will be directed si'ibstantially radially and the jets from thelower holes 12 will be directed downwardly. On the suction stroke of thepump, ball 8 is drawn to its seat so that air cannot be drawn throughthe nozzle. The nozzle can be quickly and easily taken apart and cleanedby merely unscrewing the collar 11. The ball 8 can then be removed aswell as the spray head 9, and the parts in chamber? thoroughly cleaned.Qwing to the thin material of which it is made, the member 9 iseffectively cleaned by brushing or washing thereof with a cloth and itis unnecessary to punch accumulatul. matter out of the holes therein.

From the above description it is seen that applicant has provided asimple and eflicient spray nozzle for the purpose intended. The deviceis simple, easily made and assembled and, as stated, is easilydisassembled for cleaning. The body portion 6, in practice, ispreferably made of aluminum while the spray head 9 and collar 1.1 aremade of brass, as is also the ball 8. The device has been amplydemonstrated in actual practice and found to be very successful andefiicient and the same is being supplied commercially on the milk cancleaning machines.

It will, of course, be understood, that various changes may be made inthe form, details, arrangement and proportions of the parts withoutdeparting from the scope of applicants invention, which, generallystated, consists in a device capable of earrying out the objects abovestated, such as disclosed and defined in the appended claims.

What is claimed is:

1. A nozzle having in combination, a body having a chamber in its upperend, a pas sage leading downwardly from said chamber, a ball looselydisposed in said chamber adapted to seat at the top oi said passage andclose the same, the top of said body having a downwardly and outwardlybeveled surface, a hollow cylindrical spray head of thin sheet materialhaving a semi spherical top with a multiplicity of holes tl'ierethroughabove said body and having an outwardly and downwardly inclined flangeadapted to seat on said beveled surface, and a llangedcoll-ar threadedon said body and clamping said flange against said. beveled surface.

2. The structure set forth in claim 1, said spray head having at leastone row of holes through its cylindrical portion adapted to direct fluidoutwardly and downwardly above said collar.

2.3. A nozzle comprising a body portion with a chamber therein having acylindrical upper portion, a spray head having a cylindrical lowerportion and a semi-spherical upper portion, said lower portion having acylinth'ical interior wall alining with the upper portion 0t saidchamber and also having a row of, holes the-rethrough which holes aredirected downwardly and outwardly, said semi-spherical portion having aplurality of rows of spaced upwardly and out :ardly directed holestherethrough, said spray head having a flange at its lower end overlyingthe top of said body portion, and means for pressing said flange againstthe top oi? said body port-ion and holding the same thercagainst at allcircuin'l'erentiz'il points thereof.

l. A nozzle for a milk can cleaning machine comprising a body having achamber therein with. an upper cylindrical portion and a lower roundedportion, a check valve "for said chamber, said body having a passageleading downwardly from said chamber adapted to be closed by said valve,a head of sheet material having a lower cylindrical portion alining withthe cylin dricai portion of said chamber having an upper semi-sphericalportion provided with u 'nvardly and outwardly directedcircumleremtially spaced holes, said cylindrical portion of said headalso having a row of downwardly directed holes therethrough, said headhaving an outwardly and downwardly directed flange extending thereaboutat its lower end, said body having an outwardly and downwardly beveledupper edge on which said flange is seated and having an exteriorlythreaded portion and a sleeve threaded onto said latter portion havingan inwardly directed upper portion adapted to seat against said flangethroughout its circumferential extent and press said flange down on saidbeveled upper edge of said body throughout its circun'iterential extent.

In testimony who-cot I a-[iix my signature.
